PHP FPM docker image, opcache File Cache keep disabled

Question

I'm trying to turn to Enabled "Zend OPcache - File Cache" in a docker PHP-FPM image. Currently, it's Disabled and the time to render a basic page on a Symfony website takes about 15 sec instead of 150ms.

I'm using the php-fpm-8-2-1 image on Docker which works with other containers like:

• redis
• psql
• node
• maildev
• nginx

All work fine except the php image has a part of Zend OPcache disabled.

PHP info - Zend OPcache

I try multiple solutions to turn "on" the File Cache but it didn't work.

In following, there is my docker-compose file, my Dockerfile (of php) and my opcache.ini file (I have one to override the default config.

# docker-compose.yaml

version: '3.8'

networks:
    dev:

services:
    php-fpm:
        build:
            context: php/php8-2
        restart: always
        networks:
            - dev
        depends_on:
            - db
        volumes:
#            - ./php/extensions/apcu.ini:/usr/local/etc/php/conf.d/docker-php-ext-apcu.ini
            - ./php/extensions/opcache.ini:/usr/local/etc/php/conf.d/docker-php-ext-opcache.ini
            - ./../projects/:/var/www

My PHP-FPM image build:

FROM php:8.2.1-fpm

RUN apt-get update && \
    apt-get install -y --no-install-recommends vim bash-completion libssl-dev zlib1g-dev curl git unzip libxml2-dev libpq-dev libzip-dev && \
    pecl install apcu xdebug-3.1.3 && \
    docker-php-ext-configure pgsql -with-pgsql=/usr/local/pgsql && \
    docker-php-ext-install -j$(nproc) zip intl opcache pdo pdo_mysql pdo_pgsql pgsql && \
    apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

CMD composer i -o ;  php-fpm

Consequences of it, my website on Symfony takes about 15 sec to render a page... Which should be render in about 150ms :(.

Can someone tell me what I'm doing wrong, please?

Thanks everyone!
